VLOCOIVIO'IIVE ASI-LPAN.

To all whom it may concern:

Be it known that I, HARRY A. HOKE, a citizen of the United States,residing at Al toona, in the county of Blair and tate of Pennsylvania,have invented certain new and Vuseful Improvements in LocomotiveAshePans, of which the following is a speciiication.

This invention relates to the subject of locomotive equipment and,particularly, to ash receptacles or pans of the self-cleaning type anddesigned to be operated at points where the ordinary ash pits arelocated.

To this end the invention contemplates a simple and practical locomotiveash pan construction wherein the usual and conventional pivotal dropdoors-are dispensed with, and the entire receptacle bottom utilized as adumping drop door to provide for the auto matic and complete dischargeof the material.

A further object of the invention is to provide a construction whichadmits of the ash receptacle or pan being attached directly to thefoundation ring of the locomotive boiler.

Other objects will readily appear to those familiar with the art as theinvention is better understood, and the essential features of the latterare susceptible to structural modiication without departing from thespirit or scope of the invention.

In the embodiment of the invention shown in the accompanying drawings,Figure l is a sectional elevation of a locomotive ash pan embodying thepresent invention, and showing one of the bottom dumping plates or doorsin its opened position, the other door being illustrated by dotted linesin its closed position. Fig. 2 is a sectional end elevation of the partsshown in Fig. 1 of the drawing. Fig. 3 is a sectional plan view of theimproved pan and its dumping bottom plates or doors.

Like references designate corresponding parts in the several figures ofthe drawings.

According to the present invention, the ash receptacle or pan isdesignated in its entirety by the reference character P. This receptacle0r pan is constructed of suitably assembled castings or plates and ispreferably designed to be attached directly to the foundation ring 1 ofthe locomotive boiler furnace 2. This may be provided for in a practicalmanner by constructing the ash pan or receptacle with side castings 3which Specification of Letters Patent,

directly abut against and fit the said foundation ring 1 and receive aplurality of stud bolts 4t carried by the foundation ring and havingeyes therein to receive suitable locking keys 5, although it will beunderstood that other equivalent mechanical means may be utilized toeffect this fastening connection between the body ofthe ash pan and thefoundation ring of the boiler furnace. However, it is to be noted thatthis direct fastening connection between the pan and said foundationring provides an air-tight joint between the latter and the former whichis very desirable and necessary in order to promote perfect combustionby means of the front and back dampers 6 and 7 which in the form ofconstruction illustrated are preferably made of wire netting.

In the construction shown the ash receptacle or pan P may be providedwith one or more dump compartments 8, each of which is confined betweenthe side castings or plates of the pan body, and each of which isdesigned to be covered and uncovered at its bottom by a swinging dumpingbottom plate 9. The said bottom plate 9 for each compartment constitutesthe drop door for such compartment and the same is of a size coeXtensivewith the open bottoni of the compartment so that when the door is swungto an opened position the `entire compartment is uncovered and thus freeto completely and rapidly discharge its contents.

Each swinging dumping bottom plate 9 preferably consists of a reinforcedcasting presenting a ribbed formation l() at its under side and a flatupper face 11, which latter forms the bottom surface of the receptaclecompartment when the door is closed, and one of the distinctive featuresof the present invention resides in fitting each of the plates 9 at theends thereof with the oppositely located pivot journals 12 which arefreely journaled in bearings 13 provided at the sides of the pan body.Also the opposite pivot journals l2 of each plate 9 are arrangedeccentrically, that is, in a plane at one side of the longitudinalcenter of the plate, thus economizing in the space required for thecomplete dumping movement of the plate and at the same time providingfor a quick and automatic opening thereof under the load of the pancontents when the door is released. To provide for holding each of thedumping bottom plates in its closed position the pivot journal 12 at oneend of each lOU plate has fastened thereto, as at 14, one end end of thelever when the door is in its closed position. A fixed stop 18 arrangedin the path of movement of each lever 15 serves to arrest the same whenthe dumping bottom plate or door reaches its full dumping position shownin Fig. 1.

From the foregoing it is thought that the construction, operation andadvantages of the herein described locomotive ash pan will now bereadily understood without further description, and in this connectionit is to be noted that while the present arrangement shows only two dropbottom doors, there is nothing that would prevent the construction or anash pan wherein any number of the doors may be Vused should otherstructural features permit.

I claim In a locomotive ash pan, the pan body having an open bottom, averticallylswinging dumping bottom plate arranged within said openbottom and provided with eccentrically disposed pivot journals journaledin the sides of the pan body, a holding lever rigidly fitted to one ofsaid pivot journals, a releasable locking device for the :free end ofsaid lever, and a lxed stop arranged in the path o1' movement of saidlever.

In testimony whereof I hereunto ailix my signature in the presence ofvtwo witnesses. HARRY A. HOKE.
